Ball stretching is a practice whereby a ball stretcher is fastened around a man in order to elongate the scrotum and provide a feeling of weight pulling the testicles away from the body.

While leather stretchers are most common, other models are made of steel rings that are fastened with screws, causing additional mildly uncomfortable weight to the wearer. The length of the stretcher may vary from 1-4 inches, A more dangerous type of ball stretcher can be home-made by using rope or string and wrapping it around the scrotum until the desired length of stretch is obtained.
